And determining whether the UE is allowed to access the service.

The step of the base station real-time counting the S1 transmission bandwidth occupied by the one or more operators includes: The base station performs real-time statistics on the S1 transmission bandwidth occupied by each operator according to the ongoing service of one or more operators. When a certain UE accesses a new service, or quits a certain service, or the service quality changes, the S1 transmission bandwidth occupied by the UE to which the UE belongs is changed. The base station to which the UE belongs collects and updates one or more services that are implemented by the base station. S1 transmission bandwidth occupied by the operator.

Example 1

This embodiment describes the S1 port bandwidth statistics and control when different operators occupy different cell resources under the same base station. As shown in Figure 3, Carrier A and Carrier B respectively subscribe to the S1 transmission bandwidth leased by the eNB. In the current system, there are two cells (Cell): Celll and Cell2. The users under Cell1 belong to Carrier A, and the users under Cell2 belong to Carrier 8. The base station starts the real-time statistics of the transmission bandwidth after the contracted S1 transmission bandwidth takes effect, and performs the S1 transmission bandwidth statistics for the operators A and B respectively.

UE3.

Step 1: The UE2 establishes a connection with the core network, and the base station detects that the operator to which the UE2 belongs is the operator A;

Step 2: UE2 initiates a service, and the base station queries the remaining S1 transmission bandwidth of the operator A at this time. In this embodiment, the base station periodically calculates the available S1 transmission bandwidth of each operator, and queries when the user equipment initiates the service. In other embodiments, the base station can also perform calculations in real time. Step 3: The base station compares the remaining value of the S1 transmission bandwidth of the operator A with the S1 transmission bandwidth that the UE 2 initiates to be accessed by the UE 2: if the remaining S1 interface bandwidth of the operator A satisfies the new service access, the service is allowed. Access; if not satisfied, the service establishment fails.

The base station side will update and update the S1 transmission bandwidth statistics of the operators A and B in real time. For example, when the service on the UE2 is released, the base station side updates the remaining S1 transmission bandwidth of the operator A in real time.

Example 2

This embodiment describes the S1 port bandwidth statistics and control when two operators share one cell resource. As shown in Figure 4, operators A, B, and C respectively subscribe to the leased S1 transmission bandwidth of the eNB. There are three cells Celll, Cell2 and Cell3 in the current base station. Among them, Celll is shared by operators A and B, Cell2 is shared by operators A and C, and Cell3 is shared by carriers B and C. The base station starts real-time statistics of the transmission bandwidth after the contracted S1 transmission bandwidth takes effect, and performs S1 transmission bandwidth statistics for operators A, B, and C, respectively.

At this time, there are two users of UE1 and UE2 under Celll. There are two users of UE3 and UE4 under Cell2, and there are already users UE5 under Cell3. UE1 and UE4 belong to operator A, UE2 and UE5 belong to carrier B, and UE3 belongs to Carrier C.

Step 1: The UE6 establishes a connection with the core network, and the base station detects that the operator to which the UE6 belongs is the operator C;

In the second embodiment, the UE calculates the remaining S1 transmission bandwidth in the current embodiment.

Step 3: The base station compares the remaining value of the S1 transmission bandwidth of the operator C with the expected S1 transmission bandwidth of the to-be-accessed service initiated by the UE6: if the remaining S1 interface bandwidth of the operator C satisfies the new service access, the service is allowed. Access; if not satisfied, the service establishment fails.

The base station collects and updates the SI port transmission bandwidth statistics of the operators A, B, and C in real time. For example, when the service on the UE 6 is released, the base station side updates the remaining S1 port transmission bandwidth of the operator C in real time.
